How it works
Activate Altar of Dementia by sacrificing Arashin Sovereign.
When Arashin Sovereign dies, it triggers, putting itself from your graveyard on top of your library.
Resolve the Altar of Dementia ability, causing you to mill Arashin Sovereign from your library.
Activate The Master by tapping it, putting Arashin Sovereign from your graveyard onto the battlefield.
When Arashin Sovereign enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Repeat.
This clever engine uses Altar of Dementia to sacrifice Arashin Sovereign, triggering its ability to return directly to the top of your library. From there, Altar of Dementia mills Arashin Sovereign right back into the graveyard, setting it up for The Master, Transcendent to tap and reanimate it as a 3/3 green Mutant. Every time Arashin Sovereign enters the battlefield, Intruder Alarm triggers to untap all of your creatures, instantly readying The Master, Transcendent to repeat the cycle.
